From the new perspective of service trade efficiency, this paper makes a horizontal comparison in efficiency evaluation among Shanghai Port, Singapore Port, and Busan Port to achieve the strategic goal of the free trade port. For this, the Interactive Linear and General Optimization Solver (LINGO) was applied to specific data processing. The innovations of this study are the use of the evaluation scores in the World Economic Forum for the efficiency of transportation service, quantification of the original nonquantitative evaluation items, and the optimized selection of the calculation mode by LINGO, which ensures the comparability of the results. The results show that Singapore Port's pure technical efficiency (PTE) and scale efficiency (SE) are the highest, and the data envelopment analysis (DEA) evaluation is efficient. In recent years, Shanghai Port's PTE is little higher and the SE declines, and the DEA evaluation has not been efficient. The input indicators are redundant but still improving year by year.
